ZHA to detect HS1SA-E smoke detector properly

I’m just wondering if this zigbee2mqtt

code change can be implemented in the HA core ZHA component too? I have the same HS1SA-E smoke detectors and they are recognised in the ZHA, but the alarm is not sent to HA. Can someone help me to initiate that implementation or where should I post request? ZHA implementation seems to have multiple joint projects combined.

my status is slightly different:
pairing is also OK
Pressing the test button triggers alert on HA
and after several days … no trigger anymore
after re-pairing the HS1SA, alerts are coming back

do not understand if related to time, restart of HA, stability of ZHA ???
